Technical field

The present invention relates to a kind of Ship Structure, particularly relate to a kind of triangular-section power and increase that latent ballast-free half is latent transports ship, belong to In high speed compound ship domain.

Background technology

From latter stage in 20th century, various compound (hybridization) ship type concepts constantly occur, have the most been formed to have the most to innovate and have lived The new branch of ship type technology of power.From traditional concept, owing to ship resistance and performance requires it is mutual with sea-keeping to the technology of ship type Contradiction, and the best seakeeping capacity can not be had concurrently at a high speed with low speed time simultaneously, this becomes restriction high-performance ship already The bottleneck of designs." full sea is waited " ships and light boats have become the forward position of Ship Design research.

" full sea wait " high speed operation of boats and ships to be realized, asks for first having to wave making resistance when solution is high speed and sea-keeping Topic.For displacement boat, when ship's speed increases, your moral number (Froude Number of its FuActually used simplification ForI.e. speed-length ratio) increase, when Fu Rude number increases to more than 0.5, wave making resistance accounts for drag overall ratio and is increased dramatically, speed Degree is restricted to hull speed (Hull Speed), i.e. within Fn=1.34.With self wave making and environment wave during high speed, row The sea-keeping of water type ship is also by serious challenge.Wave making resistance is formed at the boundary layer of air and water, therefore avoids or reduce and boundary The contact area in face becomes and reduces wave making resistance method, such as foilcraft the most effective with enhancing sea-keeping into high-speed craft and dive Ship, but the features such as the structure design of weight and the rigors in space and complexity all should not be used by the two as transporting ship, together Time submarine also have approximately level (in the wave effect degree of depth) rapidity, sea-keeping and maneuverability difference inherent defect.

In recent years, maritime territory controversial issue gradually causes the concern of various countries, and the defendance for this country maritime territory, especially island is To contention, need certain landing operations ability just can have the initiative in hands on the basis of relying on naval ship.Transport under water, especially Be semi-submerged ship type rely on that its loading capacity is big, the speed of a ship or plane is high, disguised strong, sea-keeping and the feature such as airworthiness is good, can be as sea power The pioneer army that amount is delivered carries out rapid deployment, it is achieved gain the initiative by striking first, it is possible to as a part for enforcement naval blockade, possesses and has The land attack ability of effect, is alternatively arranged as mother ship carrier and completes secret conveying and the recovery of special force, carry out Special Warfare Mission.? In civil area, the advantage such as low wave resistance that semi-submerged ship type transports under water and excellent airworthiness is in transport high added value goods or requirement Can fully show during " full sea is waited " operation, especially to special course line, such as Chukchi Sea, half latent opening ice transports ship More conventional opening ice transports ship and is not only dominant on navigation performance, and has obvious economy advantage.

The design of existing semi-submerged ship type is positioned the outdoor delivery of marine heavy facility (self can soak) more, and the speed of a ship or plane is relatively low, boat Row sea-keeping is poor, and the only note row by ballast water realizes the water surface and the conversion at a slow speed of half submariner state, navigates by water with buoyance in using Being main, partially surfaced condition is auxiliary (only during zero power test handling), causes existing semi-submerged ship the most not for the adaptive latent high speed operation of approximately level half Principle and molded line be designed optimize (water-drop-shaped or the long cigar shape hull exercise performance also pole when approximately level awash run Difference), the most the consideration of arrangement is done in the transport for dry goods of can not soaking.For the above reasons, existing partly diving transports ship Form is in terms of partially surfaced condition rapidity, navigation sea-keeping, boat state conversion motility, goods enclosed conveying and water ballast pollution All Shortcomings, tracing it to its cause is that ship type limits, and does not has to play half latent concept advantage in terms of rapid transit.Latent defeated for half The above-mentioned outstanding problem of fortune ship, invention one is applicable to half latent high speed enclosed conveying, has excellent rapidity and sea-keeping, disobey Bad ballast water navigates state control flexibly, is suitable in high sea situation environment the compound ship type of aerofoil profile hybridization that " full sea is waited " navigates by water.

air-breathing, and anti-cavity ability is strong, and propeller is difficult to water outlet, especially advantageous in severe sea condition.3. topside is fixed Negative lift horizontal tail increases latent attached body as major impetus, provides fixing negative lift the most all the time, to offset major part deposit Buoyancy, makes hull produce dive trend, and arrangement form reduces the disturbance of streamline around hull and the generation of Trimming Moment；Negative The lift level wing forms favourable wave-making interaction at free surface, reduces wave making resistance, and has certain vertical stability；Two The aerofoil negative lift that has a down dip makes a concerted effort to point to below ship midship, and equivalence reduces hull center of gravity, improves and transports ship stability；Airfoil Design is simple Compact, it is ensured that intensity during lift is provided.The most controlled main lift regulation aerofoil profile combines attached body acupuncture and (attacks difference load condition to lift Angle) size and Orientation is adjusted, and compensates the hull vertical force change caused because goods loads, and makes hull reach to top-up half latent Operational configuration；Spatially fix the dislocation of negative lift horizontal tail with topside, it is to avoid flow field interference between how attached body；Fitness machine is set up In the aerofoil profile node that captain boat is external, both optimized hull cargo space, and reduced again lift level wing span, improve attached body Intensity and reliability.5. stern lift regulation horizontal tail is near captain boat body stern end, provides certain lift or negative liter by controlling wing flap On the one hand power, achieves the fine setting of body lift, on the other hand achieve the balance of hull Trimming Moment and trim, pitching can Control, improves pitch metacentric stability.6. become the aerofoil section column that leans forward and cut, when awash run state, the face of striking, greatly reduce half diving Line face area, thus reduce wave making resistance and the pressure drag transporting ship partially surfaced condition；Captain boat body is positioned at below boundary layer, high The seaway load born under sea situation is greatly reduced, the least to the response of wave agitation and waving in stormy waves, stall, improves Sea-keeping；For little Water Plane, available less chain of command realizes the efficient control to pitching, rolling and heave, appearance The sensitivity that state controls strengthens；Flare lean forward form column play pressure wave (prevent on air inlet wave), improve with captain boat body and on build Bonding strength, light streamiline wire and house pipeline effect.Build on the compactest introversion lightweight is stealthy and reduce height of C.G., improve Transport ship stability, enhance vision and radar invisible.The most shallow leaching is cut the wing of striking and is provided horizontal stroke extra under awash run state Shake restoring moment, play rolling inhibitory action, compensate for the shortcoming that small-waterplane-area hull transverse stability is not enough.Specifically it is expressed as: shallow Leaching is cut the wing of striking and is cut, when awash run, the face of striking, and when hull heel, left and right wing plate depth of immersion changes, lifting surface area, Lift difference produces righting moment makes hull return back to initial rest position, it is ensured that transport the ship boat state when half latent high speed operation with Stability.9. the major control face (top airfoil) of the controlled vertical tail, of stern is positioned on the taper stern having a down dip, and easily ensures enough height And wing area, awash run state keeps full submergence, improves steerage and maneuverability.
